I agree totally! I love that you can get value, flavor, service and local support all into one lunch! They're very friendly there, and I call ahead when I'm short on time.
For $5.35 (including tax) I get my sandwich, chips, and pickle included, while others I work with wait in lunch-hour lines to have a sandwich-maker microwave their ingredients and throw it all together. And, it's $5 for a sub there (well, only 8 of their subs, actually).
When I come back for lunch with a Jon's with a "Governor's Island" (Chicken Salad, cranberries, and cucumbers), and they have a flat microwaved sub, the SANDWICH ENVY ensues. I've made a few converts just that way!
